I am planning to install a seat heater kit on my GL1800 like I did on my previous bike. It worked really well and would like to equip my G1800 with it before winter. I will use a relay to ensure that the seat heater can only be powered when the ignition is on. Before I do my own research and start testing wires with a voltmeter do you have any suggestion/idea where to get the ignition +12v somewhere under the seat?
If you are just looking for a trigger signal for a relay, then you could tap into the tail light wire at the 14 pin gray connector(C15). It’s the brown/white wire and only goes hot with the key on. Another option is to attach your trigger wire to the ACC terminal on the fuse box.
